COMBINED FITCH-GAGE.

Speciilcaton of Letters Patent.

Application m'ed my er, 1915. sernu No. 42,195

To all whom 'it may concern:

Be it known that l, Penner L. Brianna, a citizen of the United States, residing at Alton` in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Combined Pitch- Gages, of which the following is a specification.

The present invention relates to a new and improved carpentefs` tool in the forni of a gage, the principal object thereoiE being to enable the operator to ascertain almost instantaneouslv the correct :ingle at which a rafter used in tinl constrmftiou oi a roof to be cut (including the top and the base cut) and likew'se the angle at which the jack rafters are to be cut; the result bring accomplished by simply,y .setting thc several. parts of the tool iuncording'to the rise of the rafters per foot.

More specifically, the gage comprises a body having pif'oted arms at each end so that movement of the arms is indicated by certain graduations so that, for instance if there is a rise oi the rafters approximately eight inches to the foot, by setting the arms so that the numeral 8 thereon coincides with the index on the body the correct inclination al. which the rafters are to be eut is ascertained.

A still further object is to provide a device of the type in question which, being extremely simple in construction, it believed that the saine may be mamifartured and sold al. a cmnjmratvely 10W cost. Various other objects and advantages will become apparent during the continuance of the following description.

The above and other objectslwhich will become apparent, are accomplished by4 such means as are shown in their preferred form in the accompanying drawings, described in the Afollowing specification andthen more specifically pointed out in the appended claims.

ln the accompanying drawings wherein like characters designate like parts throughout the several views;

Figure 1 is a plan View of my invention.

Fig. 2 is a longitudinal, sectional view taken on line 2-2 of Fig. 1.

Fig. 3js a transverse sectional View taken on lin'e 3-3 of Fig. l.

Fig. 4 is a fragmentary View of an element used in connection with my invention.

In the drawings, the numerals 10 and 11.

designate a pair of sections which form the body portion of my improved invention, and

preferably formed of sheet metal Whereby they may be very durable and at the saine time manufactured at. a low cost. Each of the sections is provided with an upstanding fastening` member 12 adjacent its inner ond. which fastening members project through slotsI 13 in a connecting member l-fl and through the cooperation of suitably milled nuts l5 prox ide for retaining the respective sci-tions at certain adjusted positions. The said sections are also provided with rigid tus-toning members lli adjacent their outer end,- uhrh piiotally support a pan ot urne,- lll nuts itl being also proridedto rotai n the said arms in various rigid positions. l

Attention is now directed to the specific construction of the arms 17 Upon reference to F ig. l of the drawings it will be recognized that the saine are enlarged at their lower ends as at 19 and provided with a series of graduations 20. When the Said arms are adjusted, the degree of pitch is designated by the indicators 21 on the respective sections 10 and 11 whereby the operator may ascertain such degree of pitch at a glance.

The said sections 10 and 1 1 are 'further provided With depending extensions 22 which carry rigid fastening members 23 for the purpose that will presently appear. It will also be noted that suitable graduations Lil are provided on the respective sections adjacent such i'xtensions and these graduations are provided for facilitating the as certaining of the degree of pitch of the angular plates or gage elements 25 which are also provided.

The gage elements .25 above referred to are provided with a substantially V-shaped slot Ztl for the reception of the fastening members 23 whereby the said plates may be quickly adjusted and held in a rigid position relative to the respective sections.

Each of the arms 17 has one side of its enlarged or rounded end suitably graduated' and such graduations are properly identified by numerals, as indicated Inost clearly in Fig. 4, whereby provision is had for setting the arms according to a predetermined indication, such as the inclination of a rafter or other work when laying oi the Same. lf the rise in a rafter is eight inches to the foot, one of the arms 17 is set so that the not gradnationldesi muted by the numeral 8 ie opposi e the in' ex 21 on the element l() or 11 find Such arm is made secure by tightening the element li. ,By placing the instrument on a reiter 'with the inner edges of the parte 10 and 1l. against :m edge thereof, and with the arm 17 extending along :i side of the rafter` the proper angle may be luid E by drawing a. line on tbe side of the rafter correslaonding with the outer edge of thenrm 17. This gives the correct angle upon which the 'upper end of the rai-'ter is to be cut so as to lie snugly against e vertical side of thev p'urlin. The remaining arm 17 'may be set according to the required angle on whiowthe lower end of the rafter is to be cut.

Should it be required to cutcne or both ends of the refter, on en angle transversely in order to hav the end of the rafter lit close against tbc pnrlin or like art when the rafter is not disposed :it n right angle thereto, one or both o1 the til-ttes 9,5 nifty be Set with reference to the e: tien 1U or ill. These plates Q5 muy he properly adjusted according to tile irdinzvcrse :angie or bevel by having reference to the gf'adlletions :2le on the respective pci-ts or ll. These graduations 2l are formed on the are ol circles as clearly indicated in Fig. l, und the plates may be set with either edge in coincident relation. with the graduation corresponding to the bevel or transverse angle, et which the ratten or other part to be entr The outermost edge ot the plate 25 is genorally utilized as the directing edge along which the marker is drawn when indicatinv' the line of cut on the reiter or other wor to be cut. To allow for e variety of ad: justments of nach, o the` 19,1 :ttes 225, the latter are given a snbstemislly V-for1n and lim/ing tapering ends, the edges of which are adapt ed to be utilized as directing edges. The slot Q6 in each of the platee is snbstnnt'ielly of V-form to receive the threaded stud. or

2. In e device of the character described,

:1y pair of sections, means adjustably connect ing said sections, an arm pivoted to the outer end of each of said sections, each of said sections provided with e lateral excen- Sion, and n gage element movably mounted on each of seid extensions, for the purpose specified. i

3. A gegelof the tvptfspecied, including n, pair of opposite y extending sections,

ineens for udjnstnbly connecting the Sec-l tions, un arm pivoted to the outer end of euch of said sections the lower ends of said :fu-nis being enlarged and provided with a series ot graduations, said sections rovided with indicators to coperate with t e graduatione on said enlargements, an extension depending from each of said sections, said sections provided with suitable graduations in proximityY to said extensions, fastening members carried on said extensions, `and a. gage element movably mounted on each of seid extensions and ooperating with the grs duatlons on said sections.

In testimony whereof I affix my signature 1n presence of two witnesses.
